AN fittings @#$%$#@!!

So the AN fittings available in the US appear to be all even numbers.(-2, -4, -6, etc) The AN numbrer corresponds to the numerator of the hose or pipe size; ie -4 means it fits a 4/16 or 1/4 pipe or hose. The rover hoses and pipes are 5/16 by my measurements.... Of course they are!!! It would be too f--king easy to make them compatable! I'm sure this 1/16th difference is crucial to the off road performance of the legendary Land Rover. Anyway, does anyone know if AN -4 or -6 will work with Rover hose/pipe sizes or should I start shopping in the UK? I'm going to post on ORRP and see if I get any feedback.

Thanks and Happy Fourth!!!

It depends. What type of hose connections are you working with? If its a low pressure fitting and your just using a press-on flange fitting then close counts. If you are using some exotic high pressure fitting like gates or some other press fit, then I am pretty sure you have to be right on.

Made it further than half of the other guys, but the Hammers won.

You can use a 5/16" to -6 JIC adapter fitting.

Or a -5 AN compression fitting, and adapt it to a -6 AN

Summit Racing is your friend with this.

Technically speaking, they're not 5/16, they're 8mm. Of course you're quite literally splitting hairs at that point, but if you have the choice of ordering a 5/16 or a 8mm adapter, may as well go with the 8mm.
